What it is
An extract derived from the branches of Sophora japonica (Japanese pagoda tree), rich in flavonoids like quercetin and rutin that have antioxidant and anti-inflammatory properties.
How it works
The flavonoids in the extract neutralize free radicals (unstable molecules that damage skin cells) and may reduce the activity of inflammatory enzymes, helping to calm irritation and support the skin's natural barrier.
Pros
Gentle soothing potential
Early research suggests the extract may help calm skin redness and irritation, making it a good option for sensitive skin types.
Antioxidant support
Flavonoids in the extract can help neutralize free radicals from pollution and UV exposure, supporting overall skin health.
Cons and cautions
Limited human evidence
Most studies on Sophora japonica have been done in labs or on animals, so we don't yet have strong proof of its benefits on human skin.
Variable quality
As a natural extract, its potency can differ between brands and batches, making it hard to predict how well a specific product will work.
Best for
- People with sensitive or easily irritated skin looking for gentle soothing ingredients
- Anyone wanting extra antioxidant support in their daily routine
Use caution if
